Official title
A Global, Multicenter, Randomized, Dose-Optimization Phase II Study of Trastuzumab Rezetecan (SHR-A1811) in Combination With mFOLFOX6 (-1) and Bevacizumab as First-Line Treatment in Patients With HER2-Positive Advanced Colorectal Cancer (HORIZON-CRC221)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This global study is being conducted to evaluate the safety and determine the recommended phase 3 dose of trastuzumab rezetecan in combination with mFOLFOX6 chemotherapy (dose level -1) and bevacizumab as first-line treatment in participants with advanced colorectal cancer that expresses HER2, including but not limited to HER2 immunohistochemistry (IHC) 2+ "equivocal" or 3+ "positive" based on gastric cancer criteria, focused on the Western population. Encouraging data in efficacy and safety with trastuzumab rezetecan in a similar setting in China (NCT06015048) were presented at 2026 American Society of Clinical Oncology annual meeting.
